    摘要: A bi-stable projection screen includes a light diffusion unit and a bi-stable display unit stacked together. The bi-stable display unit, when actuated, selectively operates in a first mode or a second mode. When operating in the first mode (e.g., a transmission mode or a reflection mode), the bi-stable display unit receives a projection light from a front projection or a rear projection, and emits the projection light after modulation. When operating in the second mode (a non-transmission mode or a non-reflection mode), the bi-stable display unit is a pattern to become a part of a scene. The light diffusion unit receives and diffuses the modulated projection light to be perceived by human eyes.

    摘要: A low color shift polarizer assembly is provided, comprising a cholesteric liquid crystal film with a plurality of very tiny grooves which are irregularly dispersed on a surface of the cholesteric liquid crystal film. The selective reflective wavelength range of the cholesteric liquid crystal film has a long wavelength boundary ≧700 nm and a short wavelength boundary ≦420 nm. A quarter wavelength retardation plate can be disposed on the cholesteric liquid crystal film to build up the final low color shift polarizer assembly. The polarizer assembly can be combined with a backlight unit and further with a liquid crystal display to provide low color shift at large viewing angles and high brightness.

    摘要: A solution for fabricating a light diffusing sheet-like device capable of emitting light with superior brightness, that is a high brightness diffuser. The high brightness diffuser mainly includes at least two light diffusing pieces with ridge-shape structure arranged thereon, which can be either convex or concave. The convex ridge-shape structure having a plurality of large convex ridges and a plurality of small convex ridges, which are associated with a ridgeline existing in between two adjacent ridges where the large ridge and small are interlace-arranged, and the ridges along with the associated ridgelines can be longitudinally extended to the same direction. The concave ridge-shape structure is constituted the same way as the convex ridge-shape structure is, but having concave ridges. The high brightness diffuser is fabricated by stacking up the two light diffusing pieces and enabling an included angle to be formed between the two ridge-extending directions of the two light diffusing pieces.
